Drax the Destroyer (Marvel Comics)

Summary

Arthur Douglas was once a normal human with a loving wife and daughter that lived on Earth. While driving together as a family across the Mojave Desert, he witnessed a spaceship carrying the Mad Titan Thanos. Wishing to keep his existence to Earth a secret, Thanos destroyed the car and landed to ensure that there were no witnesses. While the daughter ultimately survived, Arthur and his wife died.

Thanos's father, Mentor A'Lars, realizing the threat Thanos poses, decided to create a being of sufficient power that was able to defeat him. Enlisting the help of his father, Kronos, A'Lars gathered Arthur's soul before it completely left his body and placed it in an highly empowered humanoid body. This being, now known as Drax the Destroyer, has one purpose instilled into him, to kill Thanos.
